Description

本発明は、照明器具に係り、特にはランプを保持する筐体の開口部をシェードで覆った構造の照明器具に関する。   The present invention relates to a luminaire, and more particularly to a luminaire having a structure in which an opening of a housing holding a lamp is covered with a shade.

従来の照明器具には、天井等の取付箇所に固定される筐体を有し、この筐体には、その内側に蛍光灯などのランプが配設されるとともに、ランプからの光を外部に投光する開口部が形成され、さらにこの開口部をシェードで覆った構成のものがある（例えば、特許文献１参照）。   Conventional lighting fixtures have a casing that is fixed to a mounting location such as a ceiling. The casing is provided with a lamp such as a fluorescent lamp inside thereof, and light from the lamp is externally provided. There is a configuration in which an opening for projecting is formed, and the opening is covered with a shade (see, for example, Patent Document 1).

一般にシェードは、ランプの汚れを防止するとともに、ランプからの光が直接視界に入ると眩しいので、その眩しさを低減する役目を果たしており、このため、シェードは、アクリルやガラス等からなる半透明のパネル部材を有し、このパネル部材をフレームに固定した構成のものが採用されている。このようなシェードは、ランプ交換時には取り外す必要があるため、天井等に固定された筐体に対して着脱可能、あるいは開閉可能に結合されている。   In general, the shade prevents the lamp from becoming dirty, and it is dazzling when the light from the lamp directly enters the field of view. Therefore, the shade plays a role in reducing the glare. Therefore, the shade is translucent made of acrylic or glass. A panel member having a structure in which the panel member is fixed to a frame is employed. Since such a shade needs to be removed when the lamp is replaced, it is detachably connected to a casing fixed to the ceiling or the like, or is connected to be openable and closable.

また、従来（１）シェードのフレームを天井に固定された筐体にツマミねじなどを用いて固定したり、（２）シェードのフレームに複数のＶ字状のキックばねを設け、このキックばねを筐体に設けたガイドに挿入し、ガイド内でばねが広がることによる引き込み作用によってシェードを筐体に結合したり、（３）シェードのフレームの一端側を天井に固定された筐体に対して丁番により開閉自在に取り付けるとともに、フレームの他端側にラッチ金具を設け、このラッチ金具でフレームの他端側を筐体に係止するなどの構成のものが提供されている。
実開平５−８３９２０号公報 Conventionally, (1) the shade frame is fixed to the casing fixed to the ceiling using a knob screw or the like. (2) The shade frame is provided with a plurality of V-shaped kick springs. The shade is inserted into a guide provided in the housing, and the shade is coupled to the housing by a pulling action caused by a spring spreading in the guide, or (3) one end of the frame of the shade is fixed to the ceiling There is provided a configuration in which a latch fitting is provided on the other end side of the frame, and the other end side of the frame is locked to the housing by the latch fitting, while being attached to be opened and closed by a hinge.
Japanese Utility Model Publication No. 5-83920

しかしながら、シェードを筐体に着脱可能に結合する上記（１）〜（３）の従来構成のものは、それぞれ次のような課題がある。すなわち、上記（１）のように、天井等に固定された筐体にツマミねじなどを用いてシェードのフレームを固定する構成のものは、ランプ交換時にツマミねじを緩めたり、締め付けたりする必要があるため、シェードを着脱するのに余分な労力と手間がかかる。   However, the conventional configurations (1) to (3) in which the shade is detachably coupled to the housing have the following problems. That is, as in the above (1), in the configuration in which the frame of the shade is fixed to the housing fixed to the ceiling or the like by using a knob screw or the like, it is necessary to loosen or tighten the knob screw when replacing the lamp. Therefore, it takes extra labor and labor to attach and detach the shade.

上記（２）のようにシェードのフレームをキックばねによって筐体に結合する構成のものは、（１）のようにツマミねじを緩めたり、締め付けたりする構成のものに比べるとシェードの着脱は容易であるが、ランプ交換時にはシェードを筐体から完全に取り外す必要がある点で何ら変わりはなく、依然としてシェードを着脱するのに余分な労力を要する。   The structure in which the frame of the shade is coupled to the housing by the kick spring as in (2) above is easier to attach and detach the shade than the structure in which the knob screw is loosened or tightened as in (1). However, there is no change in that it is necessary to completely remove the shade from the housing when replacing the lamp, and it still requires extra labor to attach and detach the shade.

また、上記（３）のようにシェードのフレームの一端側を丁番を介して筐体に開閉自在に取り付ける一方、フレームの他端側をラッチ金具を介して筐体に係止する構成のものは、上記（１），（２）の構成のように、シェードを筐体から完全に取り外す必要はないが、ランプ交換時にはシェードが丁番を介して筐体から下方に垂れ下がる状態となるため、この垂れ下がったシェードがランプ交換時の作業空間を制限して邪魔になり、交換作業をかえって妨害するといった不具合がある。   Also, as described in (3) above, one end side of the shade frame is attached to the housing through a hinge so as to be openable and closable, and the other end side of the frame is locked to the housing via a latch fitting. As in the configurations of (1) and (2) above, it is not necessary to completely remove the shade from the housing, but when the lamp is replaced, the shade hangs downward from the housing via the hinge. There is a problem that the hanging shade restricts the work space at the time of lamp replacement and becomes an obstacle to obstruct the replacement work.

本発明は、上記の課題を解決するためになされたもので、従来のようにランプ交換時にシェードを取り外したり、シェードが垂れ下がるといったことがなくて、簡単にランプ交換作業を行うことができる照明装置を提供することを目的とする。   The present invention has been made in order to solve the above-described problem, and the illumination device can be easily replaced without removing the shade or changing the shade when the lamp is replaced as in the prior art. The purpose is to provide.

上記の目的を達成するために、本発明の照明装置にあっては、取付箇所に固定される筐体を有し、この筐体には、その内側にランプが配設されるとともに、前記ランプの光を外部に投光する開口部が形成され、かつ、この開口部を開閉するシェード機構が配設されており、このシェード機構は、前記開口部を覆う帯状のシェード部材と、このシェード部材を巻き取る巻取機構部とを備えるとともに、前記シェード部材の端部には当該シェード部材を前記取付箇所の近傍に係止する留め具が取り付けられて構成されている。   In order to achieve the above object, the lighting device of the present invention has a housing fixed to the mounting location, and the housing is provided with a lamp inside thereof, and the lamp An opening for projecting the light of the outside is formed, and a shade mechanism for opening and closing the opening is provided. The shade mechanism includes a belt-like shade member that covers the opening, and the shade member. And a winding mechanism that winds the shade member, and an end portion of the shade member is attached with a fastener that locks the shade member in the vicinity of the attachment location.

本発明によれば、ランプ交換時には、シェード部材の端部に設けられた留め具を天井等の取付箇所から外すと、シェード部材が巻取機構部によって自動的に巻き取られて筐体の開口部が現れる。したがって、従来のように、ランプ交換時にシェードを取り外す必要がないので、シェード部材が垂れ下がってランプ交換作業の障害になることもない。このため、簡単かつ短時間でランプ交換作業に取り掛かることができ、また安全性も向上する。   According to the present invention, when the lamp is replaced, when the fastener provided at the end of the shade member is removed from the mounting location such as the ceiling, the shade member is automatically wound by the winding mechanism and the opening of the housing is opened. Part appears. Therefore, it is not necessary to remove the shade at the time of lamp replacement as in the prior art, so that the shade member does not hang down and does not hinder lamp replacement work. For this reason, lamp replacement work can be started easily and in a short time, and safety is also improved.

また、シェード部材を簡単に開閉操作できるため、必要に応じてシェード部材で筐体の開口部を覆うか否かによって簡単にランプの光量を調節することができる。さらに、シェード部材に文字や絵柄を簡単に入れるこができるため、これによって装飾的な効果を得ることも可能になる。   In addition, since the shade member can be easily opened and closed, the light quantity of the lamp can be easily adjusted according to whether or not the shade member covers the opening of the housing as necessary. Furthermore, since a character and a picture can be easily put in the shade member, it is possible to obtain a decorative effect.

以下、本発明の実施の形態について、図面を参照して詳しく説明する。図１は本発明の実施の形態における照明器具を天井に取り付けた状態を示す斜視図、図２は同照明器具を天井に取り付けた状態を示す断面図、図３は図２の符号Ａで示す部分を拡大して示す断面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a state in which the lighting fixture according to the embodiment of the present invention is attached to the ceiling, FIG. 2 is a cross-sectional view showing a state in which the lighting fixture is attached to the ceiling, and FIG. It is sectional drawing which expands and shows a part.

この実施の形態の照明器具１は、天井埋込タイプのものであり、このため、この照明器具１の取付箇所となる天井の天板２には照明器具１の取り付け用の平面視方形をした取付用開口２ａが形成されており、この取付開口２ａを通じて照明器具１を構成する箱形の筐体３が吊ボルト４によって天井の図示しない柱等に固定されている。また、この筐体３は、後述のランプ７の光を外部に投光する開口部３ａを有するとともに、その開口部３ａの周縁部から外方に張り出してフランジ部３ｂが形成され、このフランジ部３ｂが天井の取付開口２ａの周縁部に接合している。また、このフランジ部３ｂに額縁状の縁金具５が嵌着されている。   The lighting fixture 1 of this embodiment is of a ceiling embedded type. Therefore, the top plate 2 of the ceiling, which is the mounting location of the lighting fixture 1, has a plan view square for mounting the lighting fixture 1. A mounting opening 2a is formed, and a box-shaped housing 3 constituting the lighting apparatus 1 is fixed to a column or the like (not shown) of the ceiling by a suspension bolt 4 through the mounting opening 2a. The housing 3 has an opening 3a for projecting light of a lamp 7 described later to the outside, and a flange portion 3b is formed by projecting outward from the peripheral edge of the opening 3a. 3b is joined to the peripheral edge of the mounting opening 2a on the ceiling. Further, a frame-shaped edge fitting 5 is fitted to the flange portion 3b.

一方、この筐体３の内側には、例えば直管形の蛍光灯などの複数のランプ７、各ランプ７を保持するソケット８、各ランプ７からの光を筐体３の開口部３ａ側に向けて反射する反射板９、各ランプ７を点灯する図示しない点灯回路などが配設されている。さらに、この実施の形態の特徴として、筐体３内には、開口部３ａを開閉するシェード機構１１が配設されている。   On the other hand, on the inside of the housing 3, for example, a plurality of lamps 7 such as straight tube fluorescent lamps, a socket 8 that holds each lamp 7, and light from each lamp 7 is directed to the opening 3 a side of the housing 3. A reflecting plate 9 that reflects toward the light source and a lighting circuit (not shown) that lights each lamp 7 are disposed. Further, as a feature of this embodiment, a shade mechanism 11 that opens and closes the opening 3 a is disposed in the housing 3.

このシェード機構１１は、筐体３の開口部３ａ全体を覆う帯状のシェード部材１２と、このシェード部材１２を巻き取る巻取機構部１３とを備えている。そして、シェード部材１２の端部には当該シェード部材１２を上記縁金具５に係止する留め具１４がシェード部材１２にかしめ止めするなどして一体的に取り付けられている。また、シェード部材１２が巻取機構部１３から引き出される途中には引出方向を転換するガイドロール１５が設けられている。   The shade mechanism 11 includes a belt-like shade member 12 that covers the entire opening 3 a of the housing 3, and a winding mechanism portion 13 that winds up the shade member 12. And the fastener 14 which latches the said shade member 12 to the said edge metal fitting 5 is attached to the edge part of the shade member 12 by caulking to the shade member 12, etc. integrally. In addition, a guide roll 15 that changes the drawing direction is provided in the middle of the shade member 12 being drawn from the winding mechanism unit 13.

上記のシェード部材１２は、光透過性のものであれば特別な制約はなく、例えば布製の生地や、ガラスクロスの両面にシリコン樹脂をコーティングしたものなどを適用することができる。また、上記の巻取機構部１３は、市販の窓用のロールスクリーンなどで使用されている周知のものである。また、上記の留め具１４は、シェード部材１２をかしめ止めするかしめ部１４ａ、縁金具５に係合するコの字形の係合部１４ｂ、および留め具１４を縁金具５に対して着脱するために手操作されるＬ字形の手操作部１４ｃが一体形成されている。なお、手操作部１４ｃは巻取機構部１３によって過剰に巻き取られないように、ガイドロール１５近傍の縁金具５に引っ掛かるストッパの役目を同時に果たしている。   The shade member 12 is not particularly limited as long as it is light-transmitting, and for example, cloth cloth or glass cloth coated on both sides with silicon resin can be applied. Moreover, said winding mechanism part 13 is a well-known thing used with the roll screen for commercially available windows. Further, the above-described fastener 14 is used for attaching and detaching the caulking portion 14 a for caulking the shade member 12, the U-shaped engagement portion 14 b for engaging the edge fitting 5, and the attachment 14 to and from the edge fitting 5. An L-shaped manual operation portion 14c that is manually operated is integrally formed. In addition, the manual operation part 14c plays the role of the stopper hooked on the edge metal fitting 5 near the guide roll 15 at the same time so that the winding mechanism part 13 is not excessively wound.

上記構成において、ランプ７の交換時には、シェード部材１２の端部に設けられた留め具１４を縁金具５から外すと、シェード部材１２が巻取機構部１３によって自動的に巻き取られて筐体３の開口部３ａが露呈される。したがって、従来のように、ランプ７の交換時にシェード部材１２を取り外す必要がなく、また、シェード部材１２が垂れ下がってランプ７の交換作業の障害になることもない。このため、簡単かつ短時間でランプ７の交換作業に取り掛かることができる。そして、ランプ７の交換後は、巻取機構部１３によって巻き取られているシェード部材１２を引き出して留め具１４を縁金具５に係止することで、筐体３の開口部３ａをシェード部材１２で覆うことができる。   In the above configuration, when the lamp 7 is replaced, if the fastener 14 provided at the end of the shade member 12 is removed from the edge fitting 5, the shade member 12 is automatically wound by the winding mechanism 13 and the casing 3 openings 3a are exposed. Therefore, it is not necessary to remove the shade member 12 when replacing the lamp 7 as in the prior art, and the shade member 12 does not hang down and obstruct the replacement operation of the lamp 7. For this reason, it is possible to start the replacement work of the lamp 7 easily and in a short time. After the replacement of the lamp 7, the shade member 12 taken up by the take-up mechanism 13 is pulled out, and the fastener 14 is locked to the edge metal fitting 5, so that the opening 3a of the housing 3 is shaded. 12 can be covered.

さらに、シェード部材１２を簡単に開閉操作できるため、必要に応じてシェード部材１２で筐体３の開口部３ａを覆うか否かによって簡単にランプ７の光量を調節することができる。さらに、シェード部材１２の素材を選択することによって文字や絵柄を簡単に入れるこができるため、これによって装飾的な効果を得ることも可能になる。   Furthermore, since the shade member 12 can be easily opened and closed, the light amount of the lamp 7 can be easily adjusted according to whether or not the shade member 12 covers the opening 3a of the housing 3 as necessary. Furthermore, since a character and a picture can be easily put in by selecting the material of the shade member 12, it is possible to obtain a decorative effect.

なお、上記の実施の形態では、ランプ７を保持する筐体３を天井に埋め込んで使用する埋込タイプの場合を例にとって説明したが、本発明はこれに限定されるものではなく、例えば筐体３を天板に直接固定する直付けタイプ、筐体３を天板に吊り下げる吊下タイプ、筐体３を壁面に固定する壁付タイプのものに対しても同様に適用することができる。さらに、本発明は、上記の実施の形態の態様に限定されるものではなく、本発明の技術思想の範囲内において適宜変更を加えることが可能である。   In the above embodiment, the case of the embedded type in which the casing 3 holding the lamp 7 is embedded in the ceiling has been described as an example. However, the present invention is not limited to this, and for example, the casing The same can be applied to a direct attachment type in which the body 3 is directly fixed to the top plate, a suspension type in which the case 3 is suspended from the top plate, and a wall type in which the case 3 is fixed to the wall surface. .
